Abstract
The utility model discloses an alarm monitoring device for momentary interruption of a power supply system. The alarm monitoring device comprises a commercial power supply circuit and a UPS power supply circuit. One end of a R1 phase line and one end of a contactor magnetic core in the commercial power supply circuit are connected with two ends of a normally open contact switch respectively, and the other end of the contactor magnetic core is connected with a T1 line of the commercial power supply circuit. One end of a R2 phase line and one end of a sound-light alarm device in the UPS power supply circuit are connected with the two ends of a normally closed contact of a contactor respectively, and the other end of the sound-light alarm device is connected with a working zero line N2 of the UPS power supply circuit. The alarm monitoring device can effectively compensate for non-tripping condition in momentary interruption caused by time delay of a commercial power supply incoming switch and timely reflect momentary interruption of a commercial power supply and fluctuations in power systems, the sound-light alarm device can offer real-time help to an operator to find problems rapidly and accurately, thereby providing reliable guaranty for safe and stable operation of the power supply system.
Description
Technical field
The utility model belongs to a kind of electric power system power failure alert detecting device, is specifically related to a kind of monitoring device that adopts civil power instantaneous power-off in normal mains-supplied and the uninterruptible power system.
Background technology
In electric power system, according to the characteristic of electric power system and the importance of the equipment of use, adopt two kinds of patterns of normal mains-supplied and uninterrupted power supply (UPS-Uninterruptible Power Supplies) to power jointly, most equipment adopts city's power mode power supply, for guaranteeing the request for utilization under system's extreme case, important equipment need adopt the powering mode of ups power, to guarantee the security of operation of system.
In the electric power system of reality, the common faults phenomenon is the instantaneous power-off fault the most, power off time usually only is several milliseconds even shorter, the total input-wire switch setting of electric power system is sensitive, can detect this type of fault and produce disconnection, and most equipment can not be subjected to the influence of voltage fluctuation so fast in the system, this has just caused under the instantaneous power-off failure condition, if system's service entrance switch does not disconnect, can improve the stability of electric power system, reduce the influence that instantaneous power-off brings, therefore a lot of systems have adopted time-delay mechanism in the end of incoming cables, the instantaneous power-off fault that produces in delay time can not cause the disconnection of system's power supply service entrance switch, can ignore this power failure phenomenon simultaneously in overall monitor state, avoids this phenomenon of the failure to the influence of electric power system.
But in actual use, though system itself has filtered this fault, but there are a large amount of dissimilar load equipments in the system, these loads but may produce powering-off state in this fault, for monitoring the generation of this type of phenomenon, in the normal operation of assurance system, design and produce a kind of instantaneous power-off warning device, satisfy request for utilization.
Summary of the invention
The utility model proposes in order to overcome the shortcoming that exists in the prior art, and the monitoring device that provides a kind of electric power system instantaneous power-off to report to the police is provided.
The technical solution of the utility model is: the monitoring device that a kind of electric power system instantaneous power-off is reported to the police comprises mains-supplied circuit and uninterrupted power supply circuit.
The power supply of described mains-supplied circuit inserts three-phase work live wire R1, S1, T1 and the working zero line N1 of supply line respectively, R1 phase circuit in the mains-supplied circuit and an end of contactor magnetic core are connected with the two ends of normally opened contact switch respectively, and the other end of contactor magnetic core is connected with mains-supplied T1 phase circuit.
The UPS power supply of described uninterrupted power supply wiring circuit inserts three-phase work live wire R2, S2, T2 and the working zero line N2 of supply line respectively, R2 phase circuit harmony light warning device one end in the uninterrupted power supply circuit supply is connected with the two ends of contactor normally closed contact respectively, and the other end of acoustic-optic alarm is connected with the working zero line N2 of UPS supply line.
Described normally opened contact switch adopts the commercially available LA160 type pushbutton switch that has auxiliary contact lock function and pilot lamp.
Described contactor magnetic core adopts the commercially available CJ20 type A.C. contactor that has the auxiliary contact function.
Described acoustic-optic alarm adopts the commercially available audible-visual annunciator that has sound and light of alarm concurrently.
The utility model can effectively remedy not breaking situation of instantaneous power-off that mains-supplied service entrance switch delay function produces, in time reflect mains-supplied instantaneous power-off and power network fluctuation situation, acoustic-optic alarm can help for operating personnel quick and precisely pinpoint the problems provide timely, provides reliable assurance to the safe and stable operation of electric power system.
